摘要: 科学预测产品需求可以指导产业调整和行业发展。灰色理论能够减少对信息量少的系统进行主观臆断。铝的需求影响因素主要包括经济社会发展、产业结构、资源替代、再生铝利用、政策因素和资源供给等。采用GM(1,n)模型,预计2015年GDP增长率约8%,原铝消费量2 350~2 870万t,相应需要铝土矿约9 000万t。预测值通过精度检验,等级最高。分析表明,预测结果合理。

关键词: 灰色理论, 铝需求, 预测

Abstract: Scientific forecast on the consumption can guide the industrial adjustment and development. The Grey theory can decrease the subjective attribute to the less information system. The influential factors for Aluminum consumption include the economic and social development,industrial structure,substitution of resources,use of secondary Aluminum,policy,and resources supply etc.. GM(1,n) Model is used to forecast the growth rate of GDP approximate 8%,the consumption of Aluminum about 23.5~28.7 million tons,and bauxite 90 million tons relevantly needed. The forecasted value reached maximal level through accuracy assessment and is reasonable after analysis. 

Key words: Grey theory, Aluminum consumption, Forecast
